WebChlorophyll is the light-harvesting molecule central to the process of photosynthesis. Chlorophyll is synthesized through 15 enzymatic steps. Most of the reactions have been characterized using recombinant proteins. One exception is the formation of the isocyclic E-ring characteristic of chlorophylls. This reaction is catalyzed by the Mg-protoporphyrin IX … WebApr 28, 2024 · Chlorophyll is a molecule produced by plants, algae and cyanobacteria which aids in the conversion of light energy into chemical bonds. Chlorophyll is known as a pigment, or molecule that reflects …

WebThe energy culminates in a molecule of chlorophyll found in the reaction center. The energy “excites” one of its electrons enough to leave the molecule and be transferred to a nearby primary electron acceptor. A … WebQuestion 4. Textbook Question. When light strikes chlorophyll molecules in the reaction-center complex, they lose electrons, which are ultimately replaced by a. splitting water. b. oxidizing NADPH. c. the primary electron acceptor. d. the electron transport chain. WebDRAW a curved arrow mechanism for photosynthesis with the following steps. Show the flow of electrons in the drawing. 1: Absorption of sunlight and excitation of chlorophyll molecules. 2: Transfer of energy to reaction center chlorophylls, which lose an electron and become oxidized. 3: Electron transfer from oxidized chlorophylls to an electron inn crowd
